Kuzu's 356 (1961 T5)

Current issue of 356 Registry profiles a 356 that Ibrahim recently purchased in near perfect condition. An amazing car owned now by the man that is developing the 4-cam fan system.
Great find Ibrahim!

Thank you Steve,
This original beauty drives like a dream.I have owned many 356 Porsche
cars and have in my collection six cars including 1956 Carrera GS coupe
The 61 is the best.
Here is a shot for the 356 Porsche lovers.Please enjoy.
Soon we are installing the 356 S90 engine with 4 cam cooling system
in my 57 Coupe and see how the runs will turn out.

Well Guys, here she is almost ready to hit the road for a long test
drives all hooked up ready, just need to get my 12V generator
problem fixed.All 4 cylinder heads hooked up with heat sensors
and gauge under the dash with a switch I can read Cylinders#1,2,3,4
Enjoy the pictures.

Ibrahim,

Looks realy great !!!!
In a 356 even better because you cannot see that the valve covers aren't at the richt place.....
Is it an idea maybe to mount copies of the 4 cam upper valve covers at the same angle? Non functional of course?
This way when it's mount in a Spyder it's more authentical from a distance. You could make a box of it to, for example, keep some spare plugs, tools or something....

Kuzu -- I can hardly wait to see what your tests produce -- please keep me posted on the progress of the 4-cam shroud !!!

Thanks, Bruce

Kuzu did you take a cylinder temperature measurements with the origianl doghouse shroud to be able to make a comparison, would be interesting.

Friends,Thank you for the Q?'s and please enjoy some more pictures of our prototype S90 engine with original 4 cam generator stand,Double aluminum fan and original Carrera fan shroud installed on our 616 engine in a 1957 A coupe.
Some of you may already know that we started the project four years ago and still working on making the parts.
As soon as we receive our new rebuild Solex PII-40 carbs from Bieker Engineering,we will do some
long distance test runs.We did 40 miles run with the Solex carbs on the car which were not
great condition on the low RPM.Weather temp was 89F doing 75mph for 20 miles, our Cylinder
head temp in all 4 cylinders were showing 350F.Next 20 miles was a hard run 85~90 mph weather temp was little cooler 85F
CHT in all 4 was 350~360F (This was great and expected with Carrera cooling system)
Engine is new rebuild by Harry and original P/C set from Tom ( Carquip ) Crank to gen pulley is
1/1 like 4 cam Carrera engines turning the fan almost half less than the 616 pushrod engine or VW T1 engine.Engine oil cooler is up front,there is no oil cooler on the engine.
We will be posting time to time info in the \" Porsche356club.org \"
bulletin board.Please do visit the site and also here
Club member from CA.tested his Pushrod 616 C engine and he was getting around 400~450F CHT temp on 75F weather temp in 10 miles run
That is 1.8 to 1 crank to gen pulley and regular 356 engine cooling system.

Kuzu, Great to see the development coming along.

It sounds like the next challenge is data logging in the car with some better instrumentation followed by some heat soak dyno tests. The in car data logging will allow parameters to be compared Vs RPM, vs load and Vs other temps like oil and etc. Ultimately the cooling system would need to be swapped out for the original 356 tinware and etc and the same tests ran for cmparative and baseline results.

I'll have time to help you with this in the late Fall, till then I'm slammed and have no time for anything other than whats scheduled..

This work can be fun, but also very tiresome and seemingly never ending. I do it all the time and have the most ultimate gadgets to make it easier and more accurate at the same time..

Thank you Jake,
It is being long ,difficult and expensive work,and almost getting to the end
we got few more parts to build than lots of hand work and time for each fan shroud to put it together.
Hopefully we will meet in your place in near future.For now we need to check needed testing and some of the parts build in this 4 cam cooling system.
So far every part is working nice and smooth but we like to make longer trips in different altitudes and weather temp.
Here is a picture of one of the 4 cam shroud air channel being stamped.

bbgroovin,
After five years hard work,the first 4 cam Fan shroud is build in four weeks working part time,tested 40 miles on our 57 coupe and delivered to the 356 Owner.
We will still like to do the long distance drive when we get the chance.So far every part build in 4 cam
cooling on 616 Engines working great with over 200 miles on the odometer.

Almost time to start taking orders. Will most 911 alternators fit inside your replica shroud or not??

Dempwolf,
As you know the purpose of our design is the Factory original Carrera engine look.
And the parts are build Original Carrera engine parts.
But you can use 12V small diameter generator in the Gen stand as we do on the test car.There are VW shops converts 6V gen to 12V or can use 65~67 Porsche 912 generators.
